Description

The fluid reservoir of rotary compressor

Technical field

The utility model relates to a kind of rotary compressor, particularly relates to a kind of fluid reservoir of rotary compressor.

Background technology

In general, compressor is a kind of machine of compressed fluid.This compressor is by the closed container with certain inner space, is installed in the electromechanical part that can produce driving force in the closed container and can utilizes the driving force of electromechanical part and the compression mechanical portion of compressed fluid constitutes.Fig. 1 is the rotary compressor vertical structure cutaway view of prior art.As shown in Figure 1, the closed container of the rotary compressor 10 of this prior art is made of cylindrical housing 3 and loam cake 4 and lower cover 5.One side of shell 3 is provided with refrigerant import 1, and the centre of loam cake 4 then is provided with refrigerant exit 2.The electromechanical part on closed container top mainly by be fixed on cylindrical housing 3 inwalls stator 11 and the center of stator 11 and can by and stator 11 between the rotor 12 that is rotated of electromagnetic action form.30 of compression mechanical portion that are positioned at the closed container bottom mainly comprise cylinder 35 and are installed in the upper bearing 32 and the lower bearing 33 of cylinder 35 upper and lower end faces respectively.Bent axle 31 runs through the center of rotor 12 and cylinder 35, and it can together rotate with rotor 12, thereby the revolving force that electromechanical part produces can be passed to compression mechanical portion 30.The bottom of bent axle 31 is formed with eccentric part 31a, and the outside of eccentric part 31a then is with and can be rotated in cylinder 35, thereby rolling of compression refrigerant encircles 36.Do not overlap with the pivot of bent axle 31 owing to roll the center of gravity of ring 36, thus the power energy imbalance can appear when bent axle 31 rotates at a high speed in compressor, thus become the vibrative main cause of compressor.To load onto balance weight 6 and come trimming moment in order to address this problem usually to add in the upper end of rotor 12.In addition, this rotary compressor 10 is connected with fluid reservoir 13 by the refrigerant import 1 that is positioned at shell 3 one sides.Fig. 2 is the liquid storage tank structure vertical view among Fig. 1.As shown in Figure 2, the fluid reservoir 13 of this prior art mainly comprises tank body 14, support 15 and bandage 16.Wherein tank body 14 is the cylinder bodily form, and support 15 is fixed on the outer circumference surface of shell 3 one sides, and bandage 16 then is looped around on the outer circumference surface of tank body 14, and its two ends are fixed on the support 15.Bandage 16 is made by metal material usually, and forms a projection 17 on the position therebetween in order to prevent tank body 14 expanded by heating.But, owing to there is following point in the fluid reservoir of this prior art: compressor 10 and fluid reservoir 13 are assembled together and transport usually, and there is certain clearance between projection 17 and the tank body 14, made bandage 16 distortion occur if the projection 17 in handling process on the bandage 16 bumps because of certain reason, it is insecure at this moment will to cause tank body 14 to tie up.Because rotor 12, bent axle 31 in the compressor 10 and roll ring 36 and in the high speed rotary course, can produce vibration, this vibration will pass to tank body 14 by shell 3, support 15, thereby cause tank body 14 vibration and noises to occur, finally like this will cause that the consumer's is discontented.

Summary of the invention

In order to address the above problem, the purpose of this utility model is to provide a kind of can prevent the bandage distortion, thereby can reduce the fluid reservoir owing to the rotary compressor of loosening vibration that produces of tank body and noise effectively.

In order to achieve the above object, the fluid reservoir of the rotary compressor that provides of the utility model comprises tank body, support and bandage; Wherein tank body is the cylinder bodily form, and support is fixed on the outer circumference surface of shell one side, and bandage then is looped around on the outer circumference surface of tank body, and its two ends are fixed on the support; Described bandage middle part is formed with a gauffer portion.

Described gauffer portion is close on the outer circumference surface of tank body.

The fluid reservoir of the rotary compressor that the utility model provides is to form a gauffer portion that is close on the tank body outer circumference surface at the bandage middle part of being fixed on the tank body outer circumference surface, so both can cushion the dilatancy that tank body produces because of being heated, but also can avoid the distortion of being bumped of bandage in the handling process, thereby can prevent because of problems such as loosening vibration that produces of fluid reservoir and noises.

The specific embodiment

As Fig. 1, shown in Figure 3, the fluid reservoir 20 of the rotary compressor that the utility model provides comprises tank body 14, support 15 and bandage 21; Wherein tank body 14 is the cylinder bodily form, and support 15 is fixed on the outer circumference surface of shell 3 one sides, and bandage 21 then is looped around on the outer circumference surface of tank body 14, and its two ends are fixed on the support 15; Described bandage 21 middle parts are formed with a gauffer portion 22, and gauffer portion 22 is close on the outer circumference surface of tank body 14.During the rotary compressor operation that provides when the utility model, the rotor 12 at closed container central upper portion position by and stator 11 between electromagnetic action carry out the high speed rotation, drive simultaneously to run through the bent axle 31 at its center and be enclosed within rolling of bent axle 31 bottoms and encircle 36 also together rotations, thereby in the future self-circulation system and the refrigerant that enters cylinder 35 inside through fluid reservoir 20 and refrigerant import 1 compress, and will be expelled back into the circulatory system from the refrigerant exit 2 that is arranged in loam cake 4 centres through the refrigerant of overcompression then.Although rotor 12, bent axle 31 and roll the ring the 36 vibration meetings that in the high speed rotary course, produce pass to tank body 14 by shell 3, support 15, but owing to tied up the gauffer portion 22 that has on tank body 14 outer circumference surfaces, thereby can prevent the bandage 21 of distortion, and bandage 21 is close on the tank body 14, thereby the loosening phenomenons of tank body 14 can not occur, thereby also just can not occur because of rotor 12, bent axle 31 and roll tank body 14 vibration and the noise problem that the high speed rotation of ring 36 causes.
